咨询：158-0191-6798（徐梦婕） QSi3.5-3-1.5为含有锌、锰、铁等元素的硅青铜，性能同QSi3-1，但耐热性较好，棒材、线材存放时自行开裂的倾向性较小。QSi3.5-3-1.5主要用作在高温工作的轴套材料。 化学成分: 锑(Sb)≤0.002 ,铁(Fe)1.2～1.8, 镍(Ni)≤0.2, 硅(Si)3.0～4.0, 锡(Sn)≤0.25, 铅(Pb)≤0.03, 铜(Cu)余量, 锌(Zn)2.5～3.5, 锰(Mn)0.5～0.9, 磷(P)≤0.03, 砷(As)≤0.002, 杂质总和%≤1.1 力学性能: 注 :棒材的纵向室温拉伸力学性能 试样尺寸:直径40～120 硅青铜 硅青铜(silieon bronze)以硅为主要合金元 素的青铜。工业上应用的硅青铜除含硅外，还含有少量 的锰、镍、锌或其他元素。硅在铜中呈有限固溶，在 852C时最大溶解度可达5.3%，并随温度降低而减 小，但时效硬化效应不强，一般不进行强化热处理。ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" SANdbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C8%3A134217728%2C9%3A134250504%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1048576%2C32%3A32%2C40%3A32&guci=2.2.0.0.2.2.0.0&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=29.0.0&pra=5&wgl=1&tt_state=W3siaXNzdWVyT3JpZ2luIjoiaHR0cHM6Ly9hZHNlcnZpY2UuZ29vZ2xlLmNvbSISInN0YXRlIjowfSx7Imlzc3Vlck9yaWdpbiI6Imh0dHBzOi8vYXR0ZXN0YXRpb24uYW5kcm9pZC5jb20iLCJzdGF0ZSI6MH1d&dt=1603960141474&bpp=9&bdt=46&idt=24&shv=r20201026&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Db5fb53e0e30065ba-2252073159c400ab%3AT%3D1603337341%3ART%3D1603337341%3AS%3DALNI_MbsujaweaCMAJsjj7FW0iEeXag7Ug&nras=1&correlator=3075394640495&frm=23&ife=1&pv=2&ga_vid=822840946.1603960142&ga_sid=1603960142&ga_hid=899133336&ga_fc=0&iag=3&icsg=138&nhd=1&dssz=5&mdo=0&mso=0&u_tz=480&u_his=27&u_java=0&u_h=1080&u_w=1920&u_ah=1040&u_aw=1920&u_cd=24&u_nplug=27&u_nmime=50&adx=-12245933&ady=-12245933&biw=1179&bih=1071&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=42530672%2C21066923%2C21068083%2C21067655&oid=3&pvsid=1387381413354981&pem=839&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1664&brdim=912%2C22%2C912%2C22%2C1920%2C0%2C991%2C994%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=31&ifi=0&uci=0.ydir5g4e9zfm&fsb=1&dtd=63" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.ydir5g4e9zfm" data-load-complete="true"> |
